Several structures have been designed by architects of note, such as Le Corbusier, Willem Marinus Dudok, Heydar Ghiai and Claude Parent. The residences are organized mostly by nationality, although residents in each maison are not necessarily from the country implied by the naming of the building. Up to 30%-50% of the student residents in each maison may come from different nationalities. [1] Students of 132 different nationalities were living in the Cité Internationale in 2006.
